IMPROVEMENT IN WlNDNliLLS.

Specification forming part of Letters Patent No. 142,10@ dated August26, 1873; application filed April so, 1873.

To all lwhom it may concern:

Be it known that I, WESLEY J oNEs, of Davenport, in the county of Scottand State of Iowa, have invented a new and useful Improvement inWind-Wheels; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon,making a part of this specication, in which- Figure 1 is a perspectiveview, showing all of my improvement.

My invention relates to that class of windwheels in which' the speed ofthe wheel is governed by an automatic governor. My improve ment consistsin suitable appliances, whereby an automatic governor is produced, whichregulates the speed of the wheel by keeping the wings of the wheel at-such angles as are required to obtain the number of revolutions perminute that is desired, without regard to the strength of the wind.

The following is its construction and operation:

The wheel is constructed, as shown, with wings a a a a. Each wing isattached with hinges to an arm (shown at D) at each end` The inner endof the wings is attached toV the ring E at its outer edge. The ring Ehas attached to it two rods, g g,whichare also attached to the frame a uat opposite sides of the frames n n, and are hinged together at I,

which allows them to open and close. At their outward edges they areprovided with balls J J, which have attached to them studded arms thatcan be adjusted, if necessary, to secure a more perfect operation of theframes.- G represents a spring, the lower end of which is attached tothe arm I). The upper end is attached to the back4 of the wing. (Shownat H in dotted lines.)`

rIhe operation is as follows: The spring U is twisted so that it keepsthe wings a a, a at the proper angle required with a mild wind;

but should the wind increase in strength, its

force operates against the sides of the frames a n, which causes them toopen, and by means of the rods g g the ring Eis caused to slightlyrotate, which changes the angle of the wings a a a a to such an extentthat the speed of the wheel is not increased perceptibly, and as thewind ceases or decreases in strength the frame a u gradually closes,which allows the spring C to press the wings back to their proper angie.The cords F F are for the purpose of opening the governor frame. Bymeans of the rods g g and ring E, the wings a a a a. turn at rightangles to the wind, which causes the wheel to stop, and the wind canpass through without doing it any injury.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

I. The frames n n, as shown and described, for the purpose set forth.

2. The frames n n, in combination with the ring E, substantially asshown and described.

3. rIhe frames n n, ring E, rods g g, and springO, operating jointlytogether, as and for the purpose set forth.
